Abstract: A method for operating a steering mechanism (12) of a motor vehicle, wherein a steering rod (27) can be held or displaced along its longitudinal axis (a) by an electric motor (22) so that the wheel steering angle (8, 9) of at least one wheel (5, 6) on at least one vehicle axle (1) can be maintained or changed. When a force (Fext) acts essentially axially on the steering rod (27), displacement of the steering rod (27) is at least inhibited by a detent torque (RM) of the electric motor (22) and/or by a self-induced torque (Msip) of the electric motor. The invention also relates to a device for carrying out the method and to a steering mechanism, which is preferably in the form of a steer-by-wire steering system. A control unit is provided for carrying out the method.

Abstract: An assembly for plausibility checking and/or reinitializing a rear wheel steering system of a vehicle having a rear wheel steering unit, which includes at least one rear wheel actuator for adjusting a rear-wheel steering angle and a sensor for detecting the set position of the rear wheel actuator, with at least one reference sensor for detecting a reference signal and with an electronic control unit for carrying out the plausibility check and/or reinitialization of the sensor. The reference sensor is part of a vehicle unit different from the rear wheel steering unit and is designed to detect a vehicle-status-dependent reference signal. Furthermore, the control unit includes at least one mathematical model which, based on the vehicle-status-dependent reference signal, can determine a reference value and/or a reference vehicle status, with which the plausibility check and/or reinitialization can be carried out by the control unit.

Abstract: A method of operating an adjustable roll stabilizer (1) of a motor vehicle. The adjustable roll stabilizer (1) includes an actuator (2) which can rotate relative to a rotational axis (3) in order to twist two stabilizer sections (6a, 6b) connected thereto relative to one another about the rotational axis (3). The stabilizer sections (6a, 6b) are radially spaced away from the rotational axis (3) and each is coupled to a wheel suspension (7a, 7b, 8a, 8b, 9a, 9b). The actuator (2) is controlled on the basis of a system target torque specified for the vehicle, and the specified system target torque is tested for acceptability in relation to a roll torque distribution (?) that is acceptable for the motor vehicle.
